Do stop-smoking aids and support services really help?

Short answer

Yes. Nicotine replacement products, prescribed medicines and specialist support all make quitting more likely, and combining products can increase your chances further. In the UK, local Stop Smoking Services are free.

Nicotine replacement gives nicotine without the smoke.
Varenicline and cytisine are nicotine-free medicines available in the UK.
Getting to 28 days smoke-free is a big milestone.

Nicotine replacement

Patches, gum, lozenges, sprays and inhalators give your body smaller doses of nicotine to ease cravings. According to the NHS, nicotine on its own does not cause cancer, lung disease, heart disease or stroke; it is the other chemicals in cigarettes that cause most of the damage. Using a combination of products can increase your chances of quitting.

Medicines

Varenicline and cytisine are nicotine-free medicines, available through a GP or a local Stop Smoking Service.

Support

A Stop Smoking Service can help you choose products and plan your quit date. The NHS reports that people who reach 28 days smoke-free are five times more likely to quit for good.

In your plan

The planizimo quit plan works alongside any products, medicines or service you use. Mention them in the plan's final question so it is built around them.

When to talk to a professional

Speak to a pharmacist, GP or stop-smoking adviser before choosing a product or medicine, especially if you are pregnant, have a health condition or take other medicines.
